[CAN-ON] I did not include a particular job on the resume that I used to apply for my current job. I am thinking of applying for another job at this same company. If I include that job on my resume for this other job, could I get fired for omitting it from my resume for my current job?

When I was applying for job X at Company A, I did not include a particular past job experience on my resume.

I got job X, and I'm currently still working job X.

I'm looking at Company A's job board and thinking of applying for job Y at Company A.

I gotta submit a resume to apply for job Y, and I'm thinking of including the past job that I did not include on the resume I submitted when applying for job X.

If my current manager sees the resume I submit for job Y, or HR looks at it, and they notice "hey! this guy put a job that he didn't include when he originally applied for a job with us!" could I get fired?
